The IUCN status is Endangered. Cites II. Restricted-range species. The species is present in the South Central American Pacific Slope Endemic Bird Area. For the survival and recovery of this species suitable areas should be protected and existing reserves extended (IUCN 2007, Birdlife 2008). An ongoing study by Elizabeth Jones and Abraham Gallo has detected Mangrove Hummingbirds at mangroves, including those at the Río Sierpe (protected within the Humedal Nacional Térraba-Sierpe reserve), Rincón (within the Reserva Forestal Golfo Dulce), Río Esquinas (partially protected within the Parque Nacional Piedras Blancas), Río Coto, and near Sandolo (D.
